It is possible to convert all carbon components into CO2 gas and perform semi-quantitative TOC analysis!
Direct quantification of TOC is difficult due to the unique properties of soil and rock, and it is necessary to use temperature-based separation measurement. It is possible to completely decompose samples using devices with resistance heating furnaces or high-frequency furnaces for total carbon analysis. This article presents examples of TOC analysis using three total carbon analysis devices, including the presence or absence of acid treatment for inorganic carbon. Additionally, comparisons are made for samples that are hydrophilic and hydrophobic during the acid treatment process. 【Contents】 ■ Introduction ■ Official Analytical Methods ■ Analytical Conditions ■ Sample Pretreatment ■ Results ■ Conclusion *For more details, please refer to the related links or feel free to contact us.
